Check Digit Verification of cas no
The CAS Registry Mumber 441018-67-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,4,1,0,1 and 8 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 441018-67:
(8*4)+(7*4)+(6*1)+(5*0)+(4*1)+(3*8)+(2*6)+(1*7)=113
113 % 10 = 3
So 441018-67-3 is a valid CAS Registry Number.

Ring closing metathesis for the formation of medium ring ethers: The total synthesis of (-)-isolaurallene
Crimmins, Michael T,Emmitte, Kyle A,Choy, Allison L
, p. 1817 - 1834 (2007/10/03)
The total synthesis of the marine metabolite (-)-isolaurallene is described. Two approaches to the core nine-membered ether are presented both of which are based on a ring closing metathesis to close the cyclic ether.
